Adjustable sliding type abdominal operation incision retractor

Abstract

The invention discloses an adjustable sliding type abdominal operation incision retractor which comprises an annular base frame, wherein the annular base frame comprises an annular fixing frame and a supporting assembly arranged at the bottom end of the annular fixing frame; and a traction assembly which comprises a plurality of groups of sliding assemblies and traction assemblies, the sliding assembly comprises a sliding seat and a winding mechanism embedded in the sliding seat, the sliding seat is arranged in a sliding rail on the fixing frame in a sliding mode, the winding mechanism is used for winding a traction arm, the head end of the traction arm is connected with a clamping assembly, and the clamping assembly is clamped on the traction assembly. According to the adjustable sliding type abdominal operation incision retractor, the annular base frame and the matched traction assembly used in cooperation with the annular base frame are arranged, so that the position direction and the traction force of the traction hook are effectively adjusted, and the operation view field is fully exposed.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an adjustable sliding abdominal operation incision retractor. Background technique [0002] General surgery is a clinical discipline that treats liver, biliary tract, pancreas, gastrointestinal, anorectal, vascular diseases, thyroid and breast tumors and trauma and other diseases with surgery as the main method. Abdominal surgery in general surgery (surgical treatment of abdominal visceral diseases) Most of them need a sufficient field of view, and the exposure is limited by the tension of the bilateral costal arches and abdominal wall muscles. During the operation, surgical retractors need to be used to overcome the tension and pull the surgical incision for surgical operation. [0003] When performing abdominal surgery, the abdominal incision needs to be retracted and kept in a retracted state. Similarly, the incision also needs to be retracted during thoracic surgery....

AI Technical Summary

Problems solved by technology

[0004] One: the existing surgical retractor has no fixing device, and only relies on the operator to use the traditional single retractor to pull and fix the abdominal surgical incision with his own arm muscle strength. Trembling cannot be fixed accurately, causing the retractor to be pulled apart during the operation, inaccurate, and the surgical field of view is limited;

[0005] Second: the existing pulling hook can only adjust its stretching force through the position of the pull rod, which has the problem of inconvenient force adjustment. At the same time, its pulling angle is not easy to change, and it is very inconvenient to use;

[0006] Third: Although there are some devices on the market at present, these devices are scattered and self-made, resulting in the poor adjustment performance of the retractor during the use of the device, which cannot be firmly fixed, and then makes the muscle pulling force when retracting. Smaller, and sometimes because the retractor is too large, it will affect the surgical field of view, inconvenient clinical use, time-consuming and laborious, reduce the stability of the surgical operation, affect the smooth progress of the surgical operation, reduce the efficiency of the operation, prolong the operation time, and inconvenience the operation. application limited
